POLICE tried to get serial killer Peter Tobin to reveal information about other murders he is suspected of committing before he died. 

Speaking after Tobin's death was announced today, Detective Chief Superintendent Laura Thomson, head of major crime at Police Scotland, said officers tried to get the notorious murderer to "do the right thing". 

Police have long suspected Tobin had more victims and hoped he would give up his secrets before he died in prison, however, he was unwilling to give them any information.

DCS Thomson said: "Our thoughts are with the victims of Peter Tobin, their families and friends.

"Recent attempts to encourage him to do the right thing and share any knowledge he may have which could assist the police were unsuccessful.

"While we have no current lines of investigation into Peter Tobin, we welcome any information in relation to his activities."

Tobin was serving a life sentence for raping and murdering Polish student Angelika Kluk, 23, and hiding her body under the floor of a Glasgow church in 2006.

The killer was also serving life terms for the murders of 15-year-old schoolgirl Vicky Hamilton, of Redding, near Falkirk, in 1991, and 18-year-old Dinah McNicol the same year. Their bodies were found 17 years later, buried in the garden of his former home in Margate, Kent.

Police believe he is responsible for the murders of other women because he had at least 40 aliases and 150 cars during his life.
